Element Construction & General Information

Thermal Tubular-Calrod heating elements are the most versatile of all electric heating elements and are widely used as the main source of electric heat for the domestic, commercial, industrial and scientic areas. With a vast range of sheath materials, shapes, voltages and wattages; they can be used in many applications.Tubular elements can be immersed in liquids, cast into metals, clamped, placed in vessels and ducts to heat gases or simply used as radiant heaters for a variety of processes. They are easy to install, require low maintenance and have excellent internal electrical insulation and heat conduction.

Thermal Tubular-Calrod heating elements are manufactured with a resistance coil of nickel-chrome wire centrally located within a metal sheath tube. Terminal pins are fusion welded to each end of the resistance coil. These terminal pins are the cold zone of the heating element. The resistance coil assembly is stretched within the tube and lled with a magnesium oxide powder which electrically insulates the assembly from the outer sheath of the element. The magnesium oxide powder has excellent heat transfer properties and when combined with an evenly stretched resistance coil, a uniform heat is achieved along the length of the heating element. Once lled, the heating element is then roll compacted which compresses the magnesium oxide powder to a rock hard construction. This protects the resistance assembly from atmospheric corrosion and mechanical damage. The heating element is then trimmed at each end to expose the terminal pin. Silicone insulators are used to insulate the terminal pin from the outer sheath of the element and a terminal connection is tted. Various terminals, anges, mounting bushes or plates, heat dissipation ns, terminal boxes and more can be tted to suit all installations.

4.1

What is the IECEx Scheme?

What is the ATEX Directive?

Hazardous areas can be found in a range of industries where explosive atmospheres are present. An explosive atmosphere might be caused by the presence of ammable gases, liquids, vapours or dusts. Examples of these areas can be found in places such as petrol stations; sewage treatment; oil/gas reneries and processing facilities; mining; laboratories and more.

Minimising the risk of ignition within a hazardous area is paramount to ensuring the safety of both equipment and workers operating within that area. In order to assist in standardising the level of safety in these areas, a variety of certications can be achieved based on the product, use or location.

For electrical equipment used in various countries, the International Electrotechnical Commission (IEC) provides a set of standards relating to various aspects of ignition protection. The IECEx Scheme is used in a number of countries throughout the world, including Australia.

According to the IEC, “the objective of the IECEx system is to facilitate international trade in equipment and services for use in explosive atmospheres, while maintaining the required level of safety.” ¹In this scheme, the Ex ‘d’ and Ex ‘e’ classications are found to be the most commonly used for electric heaters in hazardous areas.

The ATEX directive is a European certication designed to ensure that products sold in the European market are of high quality and safety standards (similar to the Ex Scheme).ATEX certication is widely approved and used in both the European and South East Asian markets.

4.4

ThermalEx® End Sealing

The importance of end sealingThe main cause of earth leakage trip issues is moisture ingress through the element ends.This leads to low insulation readings and subsequent element failure over time.

To eliminate this problem, Thermal Electric uses a twin sealing process on all of its ThermalEx heaters, which guarantees high insulation resistance readings for years to come.

Thermal’s end sealing procedure Heating elements are placed into a vertical dehydration oven for a minimum of 48 hours and allowed to completely dry out.

Insulation tests are performed and must be greater than 500MΩ before the sealing process is carried out.

Sealing process 1 (10mm) is carried out while the heating element is in the hot state(110°C minimum surface temperature).

Heating elements are placed for the second time into the oven for a minimum of 36 hours.

Insulation test performed - greater than 500MΩ minimum reading allowable.

Sealing process 2 (5mm) is carried out while the element is in the hot state.

Once sealed, insulation and Hi pot tests are performed.

TEE’s in house test results (shown below) verify the twin sealing process and guarantee’s the reliability and longevity of the unit.

Squeeze test and then immersed in 20-24°C water for 45 minutes. Result: 200MΩ Insulation test

Environmental chamber test at 90°C. 95% relative humidity for 4 weeks. Result: 200MΩ

Immersed in 20-24°C water for 28 days. Result: 200MΩ

High temperature oven at 125°C for 6 weeks, removed and placed in sub-zero temperatures for 72 hours. Result: 200MΩ

Element assembly into Flange or Enclosure

Double Ferrule / Double Bite Compression Fitting - For easy individual heater element replacement

Double Ferrule Compression ttings are torque free, self-aligned mechanical grip ttings that are an industry standard for the chemical, bio-technology, semi-conductor, oil and gas industries to name a few.The complete assembly is made up of four parts (body, front ferrule, back ferrule and nut) that oer excellent leak-proof performance in vacuum as well as in low and high pressure applications.The back ferrule provides an anti-vibration hold on the heating element and leak-proof sealing is guaranteed at high operating temperatures.The two ferrule design oered provides a leak-proof seal at three separate points and can adjust to temperature cycling while eliminating damage to the element sheath normally caused by inferior ttings.

The heater element is inserted into the process ange or Ex ‘d’ enclosure via means of the four piece Stainless Steel compression tting. The body of the compression tting has an NPT thread that is designed for high pressure applications. The general arrangement and layout of the tting entry points have been designed so as the integrity of the ange is maintained to the existing design codes. Easy removal and replacement of individual heating elements can be achieved without the need to replace the complete anged heater bundle.

Element assembly into Flange or Enclosure

Stando Flange Heater Ferrule Arrangement- For use on Compact High Powered ThermalEx heaters

Tungsten Inert Gas (TIG) welding is highly resistant to corrosion and cracking over long time periods and is ideal for use when working with many of the exotic materials that are required for the Petrochemical, Chemical, Oil and Gas industries.It is the preferred choice when ThermalEx heaters are required to be installed into a process area that allows for the maximum kilowatt rating achievable with the minimal amount of space used.

Thorough cleanliness and preparation are imperative in achieving the best results with numerous inspections and quality checking performed before a single weld is committed to. 316SS stando ferrules are TIG welded into the process ange or base of the ThermalEx enclosure that guarantee a high quality, strong and clean weld to prevent the occurrence of oxidisation. All element ends are heat treated and normalised numerous times prior to being TIG welded or silver brazed into position. This process relieves stress on all element to ferrule contact points ensuring stress fractures do not occur during assembly and most importantly at the customers process facility. Various exotic ange and ferrule materials are available to suit customers requirements.

The general arrangement and layout of the ferrule/element entry points have been designed so as to maintain the integrity of the ange and to comply with existing design codes and pressures.

EDH Handing Side

To improve the eciency of TEE Electric Duct Heaters, Thermal designs all units with a specied handing side based on the customers requirements and site limitations.

By selecting a handing side relevant to the particular duct installation, on-site servicing is made much easier by facing the unit in a more easily accessible direction.

Determining the best handing side for an electric duct heater also optimises the performance of the unit by allowing for much more thorough over temperature monitoring based on the position of the unit within the duct.

The handing side is based on the ductwork that the unit is being installed into when looking down the duct with the airow coming towards you. The handing is then specied as either Left hand side or Right hand side.

As an example, the picture below displays Left hand side handing

When ordering, please specify the handing side required for each unit you require.

If you are unsure of the handing side needed, our design and sales team can assist in determiningthe best solution for your situation.

Evapodry Condensate Removal Tray

Suffering from unwanted condensate from your airconditioning unit?

Evapodry can solve this problem by evaporating the condensate from the collection tray under the split system’s compressor.

A new and improved control unit ensures a more reliable evaporation process. The probe senses condensate that has accumulated in the tray and energises the heating element.When the probe senses that the liquid has evaporated, the heating element is de-energised.

The electric heating element together with its condensate sensing probe, fits inside the collection tray as an integrated unit. All electrical terminations are inside an IP55 rated enclosure.

The condensate collection tray is stainless steel measuring 400 x 400 x 55mm deep, with the integrated heating element and control box fitted to the front.

Specifications

Probe senses condensate level and energises or de-energises the heating element.

Heating Element 240V 1000W or 2400W

Enclosure is IP55 rated with weatherproof exible conduit entry, and termination is by the 1 metre exible 3 core lead with a 3 pin 10 amp plug.

Evaporation rate is one litre per hour (for 1kW unit) or 2.5 litres per hour (for 2.4kW unit) and this may vary dependent upon atmospheric conditions

Condensate tray is stainless steel 400 x 400 x 55mm deep. Other sizes to order

Element safety cover fabricated from perforated stainless steel

The Evapodry tray conforms to health and safety standards in accordance with Plumbing Industry Commission - Section 7 part E.

Electric Immersion Heaters

Electric Immersion heaters are extremely useful in many applications. High heating eciency and accurate control are maintained due to the heat being generated within the solution.Immersion heaters are easily installed and are often used to heat liquids, viscous materials and solids with low melting points. Some common substances include solvents, oil, water, plating baths, salts, wax, paran, asphalt and molasses.

Design of the shape, sheath and mounting are specically tailored to the application.The heat absorption rate of substances will often determine the heat intensity (watt density) of the element. Usually low or mild heat is used for oils and soft metals and more intense heat is required for water and salts.

For accurate temperature control a thermowell is tted which then allows for single or 3 phase thermostat inclusion.

Most of our product range is manufactured in stainless steel or Incoloy element sheaths. Thermal can, however, design specic heaters with dierent sheaths (such as Titanium), shapes, sizes, wattages and voltages as required for your application. The heater mounting can also be designed to suit the application and vessel accessibility.

Types of Immersion Heaters:The most common method of applying heat to tank or vessel contents withoutlimiting work area are: Screw In - For small to medium size containers Over The Side - A heavy duty element for portable situations Withdrawable - Tubular or Ceramic Bobbin

Withdrawable Type - Tubular

Stainless Steel sheathed alternative to the standard ceramic bobbin type. The withdrawable tubular has been designed and manufactured to outlast its ceramic counterpart, which is fragile and will deteriorate much sooner through physical damage. Tubular withdrawables are suitable for applications where replacement or repairs are to be carried out without disturbing the contents of the tank.

InstallationThis is achieved by inserting the withdrawable tubular element into a nominal diameter pipe - commonly known as the thermowell - ranging from 50mm diameter for standard units, up to 100mm diameter for specials. The thermowell may be a permanent xture of the tank or it can be supplied as a separate removable tube with 2” BSP boss which can then be tted to a mating tank socket.

FeaturesRobust, suitable for harsh conditions and extremely resistant to mechanical or physical abuse, or where vibration may occur.

ApplicationsSuitable for all solutions where drainage of the tank is impractical and where direct heating is not achievable or recommended. Materials such as bitumen, wax, fats and oils require low element surface temperatures to prevent product degradation.

Options Can be manufactured in Stainless Steel, Incoloy or Titanium Various wattages and voltages Various element diameters Can be manufactured to Zone 1 Class 1 standards Several terminal variations

HOT STICKSHEATH

HOT STICKREPLACEABLE

ELEMENT

The Hot Stick range of heaters is made for use in the electroplating, metal nishing and chemical industries.It is an over the side type heater and is available in three dierent sheaths - Quartz, Stainless Steel and Titanium.The main criteria for selecting the appropriate Hot Stick is to know what solution it will be heating. Pleasecontact us to determine the correct sheath material required for your application.The wattage required to heat the load to the desired temperature in an acceptable amount of time must also be determined as well as the depth of the tank being used and the level of the liquid being heated. The heated section must be covered by liquid at all times (refer to page 10.18).The following table shows the Hot Sticks dimensions and accompanying elements.

A typical installation will require the following selections to be made:For example, when ordering a 3kW Vitrosol Hot Stick for a 1000mm deep tank the following parts need to be ordered: Vitrosol sheath (1000mm) - HSVS1000 Element (3kW) - HSE30-1000 Lead assembly (2m long) - HRC2 Other components to consider: Heater guard (PVC or Polypropylene - see below) Mounting bracket (over page) Liquid level and temperature control (if required, see page 10.18)

Heater GuardsVitrosol (Quartz) HSVS and coiled Teon HSTEFE sheaths require a fully enclosed protective guard.Use PVC for solutions below 70°C and Polypropylene for solutions up to 100°C. (Except for chrome and nitric solutions)

What are Load Banks?

The necessity and dependence on power at mining sites; oil and gas refining; in hospitals; transport and many other essential services has meant a rapid growth of back up generators and UPS systems for back up power. The increase of computers and telecommunications equipment demands faultless performance in the event of power down conditions. This can only be fully achieved by resistive load testing the stand by systems on installation and at regular intervals.

The life and efficiency of diesel generators can be greatly reduced when running underloaded, causing damage to the engine, to a point where engines could stall or completely fail to start when they are needed most.

Only resistive load banks can guarantee the ultimate operating conditions and efficiencies of stand by generators. Auxiliary equipment such as resistive load banks ensure regular and reliable load testing can be performed without interruption to mains power supply and leaving you confident that your emergency power system will function during any mains power interruption.

Regular load testing also ensures back-up generators are used, which maintains the life of its parts which can deteriorate or fail if never used. Build-up of dust, water and other elements in outdoor situations can affect the efficiency of your back-up power system.

Drum Heater Jackets - 205L Drums

Thermal Electric Drum Heater Jackets are specially designed products using the latest advance in electric heating element development.

Simply, inexpensively and with safety, you can heat 205 litre drums of your sensitive and valuable product without the expense of building a hot room - our thermally insulated flexible heater jacket simply zips up to form a miniature hot room around your drum.

Operation of a Thermal drum heater jacket uses only 500 watts of electrical power. That’s about 50c to heat a 200 litre drum of typical product over twelve hours (based on average commercial electricity rates). Compared to alternatives that can cost nearly 3 times more, our drum heater will save you money and energy.

The unique carbon-film electric heating elements featured on Beyond 2000 have been selected to ensure the integrity of your product is preserved throughout the heating process. Heat is spread evenly over a wide surface area - about one square metre - eliminating ‘hot spots’ and ensuring even distribution.

Because the heating elements don’t contain metal wires or resistors they won’t deteriorate with repeated use. Being made from carbon/glass fibre they can actually be cut, torn or punctured without appreciable loss of performance. In this unique product where they are protected from damage, with ordinary use, you can expect them to last indefinitely - no more element replacements!

U-Bend-It Tubular Heating Elements

Thermal Electric manufacture annealed straight length heating elements in two element sheaths: Incoloy sheath for water, plate and air heating; and Stainless Steel for oil heating. U-Bend-It (UBI) elements are designed to be bent by you on site and therefore eliminate the need for one o specials where possible, thus reducing down time and saving you money.

UBI elements can be bent to any shape of your imagination as long as they are bent between the two cold-hot zone junctions and a minimum bending radius of two times the element sheath diameter is achieved. A minimum of 10mm distance is required from the cold-hot junction to the centre of the bending mandril to reduce the risk of breaking.

U-Bend-It elements come as a straight element with terminals only or tted with 3/8” BSP brass bushes, which are very popular in the commercial cooking industry and are used for hot food bars and bain maries.

Special voltages, wattages, lengths, diameters and sheath materials are manufactured to the customer’s request.

Bending Instructions

All Thermal U-Bend-It elements are supplied with the ‘centre’ and ‘no bend’ zone marked on the element sheath.

When the element shape is determined, ensure all dimensions and bends start from the centre mark - this will ensure that the element bushes, terminal ends and the cold-hot zone nish evenly in length.

Ensure that the minimum bending radius of 16mm is adhered to (32mm bending mandril), this will eliminate element breakage.

Thermal U-Bend-It elements can be clamped and bent using a vice, pipe or mandril, a bending lever or simply by hand - as long as there are no sharp edges that may cause damage to the elements.

Thermal Nozzle Heaters for Injection Moulding

Thermal nozzle heaters have been designed to last and reduce down time with high watt density capabilities to allow maximum temperature ratings and faster heat penetration into the nozzle.

Thermal nozzle heaters are 6.35mm diameter stainless steel tubular roll formed, making them robust and eliminating the problems that normally occur with conventional mica nozzles.

Operating temperatures of up to 600°C are achieved with outstanding reliability and a long lasting life. With the multi-form construction, this heater can be opened and tted easily without causing the damage that may normally occur with mica elements.

A Thermal Low Prole nozzle heater is also available with all of the above capabilities as well as elements of 4mm diameter stainless steel tubular roll formed. They are used in applications where there is limited space around the nozzle. The LP type is available with the same dimensions and wattages as the TS and SN type nozzle heaters.

All Thermal nozzle heaters come with 1 metre double glass insulated leads and 300mm tinned copper braid as standard. Many other options are available.

The two basic designs available are:

Thermalfold Cartridge Heaters

Thermalfold high watt density cartridge heaters are of a unique design and are the latest in electric heating technology.

Thermalfold Cartridge elements are manufactured 0.1mm to 0.5mm under-size to slide easily into the hole size specied. When energised, they heat up and spring open due to their folded construction. While in the heated condition, they are a snug t and impossible to remove.On cooling, they contract back to their original diameter and become easy to remove again. Conventional cartridge heaters would normally fail under these conditions.

The maximum element temperature is 800°C. Work temperatures of up to 600°C are therefore achievable, depending on the application.

Thermalfold cartridge heaters range in size from 6mm to 25mm diameter,with various lengths available on request.

Thermalfold cartridge heaters are specially manufactured to suit your requirements.When ordering, please specify the following dimensions (as per diagram below):A - Heating length.B - Overall length of Thermalfold.C - Length of terminating leads with or without metal exible conduit.D - Hole size in which Thermalfold is to t.E - Voltage and wattage.

Thermal Band Heaters

Thermal Band Heaters have been designed to last and reduce down time. Band Heaters have high watt density capabilities which allow maximum temperature ratings and faster heat penetration into the barrel.

Thermal Band Heaters are manufactured in 6.35mm and 7.9mm diameter stainless steel tubular roll formed construction, making them robust and eliminating the problems that normally occur with conventional mica band heaters.

Operating temperatures of up to 600°C are achieved with outstanding reliability and a long lasting life. With the multi-form design, these heaters can be opened and tted easily without causing damage to them that may normally occur with mica elements. A uniform and greater heating area around the barrel is made possible due to this construction, whereas a mica band heater for applications with thermocouple holes and cut outs may, in many cases, heat only half of the area that the element has been designed for.

Thermal Band Heaters come standard with 2 metre exible lead and plug.If desired, a plugall assembly or terminal enclosure can also be tted. The two designs available are BH type and DBH type.

Explanation of Infrared Heating

Infrared heating is a misconceived technology that many feel is dicult and complicated to apply. While the theory can be complicated, it is far easier to apply when guidance and understanding is given on various heating methods best suited to your application.

The main modes of transferring heat are:

Convection HeatingWhere heat energy is transferred from a higher temperature region in a gas or liquid to a lower temperature region as a result of movement of masses within the gas or liquid,eg. tank or vessel heating.

Conduction HeatingWhere two masses of dierent temperatures are brought into contact with each other and heat is transferred from the hotter to the cooler body, eg. platen heating and extrusion barrels.

Radiation HeatingWhere Infrared Radiant energy is transported through space by electromagnetic waves without the need of a conductive medium, allowing heat to be delivered in concentrated areas at very fast rates. Electromagnetic radiation is broken down into four categories:

Ultraviolet | Infrared (Short, Medium and Long wavelength) | Microwave | Induction

Radiant infrared heating is used in many industries, such as:

Textiles Miscellaneous ProcessesTo set nylon and perlon threads Drying and curing of paint and powder coatingsDrying washed and dyed fabrics Ink drying Preheating mouldsFood Evaporation of waterBaking Maintaining precise environmental temperaturesKeeping food warm Drying of skins and colour spraying of leatherPackaging of food products

Plastics & Rubber Pulp & PaperThermoforming Adhesive activationVacuum forming Drying of pulp paperLaminatingPre-heating rubber prior to extrusion

Thermalfold Bolt Heaters 18.1

Product Range 18.2

AUSTRALIA


18.1

Thermalfold Bolt Heaters

Thermalfold Bolt Heaters are used as an aid to tighten large bolts in heavy machinery and equipment. When inserted into a drilled hole in the bolt, the Thermalfold Bolt Heater rapidly heats the bolt, causing expansion and increasing the bolts length. This allows the nut to be further tightened. When the heater is switched o and removed, the bolt begins to cool and contracts to its original length, ensuring an extra tightened assembly.

Thermalfold Bolt Heaters are of a unique design and can be used in holes which have been drilled up to 0.5mm larger than the bolt heater diameter. When energised, the elements heat up and spring open due to their folded construction. This ensures a quick heat transfer to the bolt. While in the heated condition they are a snug t and impossible to remove. On cooling, Thermalfold Bolt Heaters contract back to their original diameter and become very easy to remove. Conventional bolt heaters will fail under these conditions. A roll compacted high grade stainless steel construction enables a maximum heater temperature of 600°C giving a faster heat up time, with minimum heat transfer or loss to the area surrounding the bolt.

Bolt heaters are used in industries such as building and construction, boiler manufacturing, power plants, mining, shipyards, large machine and die manufacturers. Typical applications include large compressors, turbines, pressure vessels, steam generators, engine heads, large cylinders and die blocks.

20.1

Calculation for Superheated SteamExample:340kg per hour of steam with 90% quality, having an inlet gauge pressure of 700kPa is to be superheated to a temperature of 230°C. How many kilowatts of power is required?

From the reference guide (see next page): 1. Plot a point equalling 700kPa on the centre reference line of the pressure and saturated temp scale (P).

2. From that point, mark a line through 90% on the quality scale (Q) to the watt hour/weight scale (W). The answer is 82.5 Watts/kilogram.

3. Note that the saturated temperature of steam at 700kPa is 170°C. A temperature of 230°C is required, therefore a 60°C temperature rise is needed.

4. From the point of 700kPa plotted on the centre reference line of P, mark a line through 60°C on the S scale to the W scale. The answer is approximately 200 Watts/kilogram.

5. Subtract 82.5 from 200 = 117.5

6. Power required = Weight x Watt hour/kilogram = 340kg x 117.5 = 39,950 Watts Always add 20% for loss + 7,990 Watts Total power = 47,940 Watts Answer = 48kW

Denitions

Saturated Temperature is the temperature at which water boils at a given pressure. At zero gauge pressure the temperature is 100°C (212°F), as steam pressure increases the saturated temperature increases - refer to the P reference scale.

Quality of Steam is the amount of moisture present in the steam, which is measured as the percentage of the total weight. Quality of steam 100% minus the percentage of moisture content, therefore dry steam has 100% quality.

Degrees of Superheat is the increase of steam temperature above the inlet saturated temperature.

Watt hour per Weight is the power required to superheat the steam above the saturated temperature. This is known as Watts per hour per kilogram (pound) required.

Weight of Steam per hour is the ow rate of steam which will be passing through the electric heating unit per hour. This information is vital for the most ecient design of the heater.

Formulae and Conversion Tables

To calculate kW required to raise the temperature of a product, the following formula may be used. This formula provides net kW to raise temperature by a desired degree in a desired time. It does not allow for ineciencies due to heat loss through insulation etc. or changes of state.

V x p x Cp x ΔT = kW required t

V = Volume required (m3)p = Density (kg/m3)Cp = Specic heat capacity (kJ/kg.K)ΔT = Required temperature change (°C)t = Required heating time in seconds

Note:1. (V x p) can be substituted by kg in this formula when heating solids such as metals.2. 1000 litres = 1m³

For ow line heating use m³ per hour ow rate to achieve kW and/or ΔT.

For more accurate check use the following formula:

kW x 3600 = m³/h (For water only) 4.187 x ΔT

Forced air heating formulaExample:Air is circulated through a heater duct by a 1000CFM blower. The air enters the duct at 35°C and is heated to 120°C

Select one of two formulae: 1. kW = m³/s x ΔT x 1.278

2. Convert 1000 CFM to L/s (refer to table) = 1000 x 0.472 = 472 litres/sec

kW = L/s x ΔT = 472 x 85 783 783 kW = 51.25 20% safety factor = 10.25 kW = 61.50

The heaters required will total 62kW
